LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Feb. with Application filed July 29, 1909. Serial No. 510,275.

110 all whom it may concern:

B0 it. known that I, lAlS'tl-Ilt l5. h'inmnn, n oitjizenot, the UnitedStates, residing in the city of New York, borough of Manhat- Ncw York.have: invented a certain new and useful \JHJPIOYCHKIW- in Loose-LeafBinders, of -l lch the following is a specification.

The invention relates to that class of binders 1n which theniotchedleaves are A teccivgcdon posts and held between bars attached to thelatter. and the object, of the invention isto provide a binder in whichthe bars may he separated for the introducio' tio n or reinoval ot'leaYes without detaching,

.the parts, and in which the. posts may be .lepgthencd or shortened toaccommodate a greater or less number of leaves as required.

flAnothrr important object is to provide 2i n'reans .for insuringagainst. accidental separation of the parts, and for compressing ffandholding the leaves.

" .The accompanying; drawings form a part of this specification and showan approved i v, t t n 2F i0 1 n of the mechanism employed, with the"leayes'and melosmg covers omitted.

Figurel is an elevation showing the posts, hars; and compressorcondihoned for service. Fig. 2 IS a planvicw of the top-bar.

li fl ilfltis is a horizontal section through the on the line 3-3 inFig. 1, showing the compressor in plan view. partly in horijzontalsection. Fig. 4 is a vertieal'section, fp'artly in elevation, showingone-0f the jl gposts, and portions of the top-bar and hottoin-bar. inthe locked condition. Fig. 5 is a similar view showing the same parts inthe open or expanded condition. Fig. 6 is a transverse section throughthe top-har.

will" 7 is a top View of one. of the postsl gimilar letters of referenceindicate the same parts in all the figures. r

The bottonrhar A is shown as ti strip of metal of suitable thicknesshaving sockets A screw-threaded internally to receive thecorrespondingly threaded lower ends of the posts which are. thus securedto the lower bar. a The posts 13 are short rods sored-threaded tomatchto the sockets A or, as',sh0\vn. to'

match to similar screw-threaded ,axial holes in extension sections B oflarger'(' ameter than the rods B and having nipples B received in thesockets or another extension section, by thus joining several extensionsections together and to the lower lmr A the posts may lielrent'z'tliened as found herrssary. Each post it is ltttltiFt'tl hp :1tulle oi sleeve tthe same external diameter as the extension 15. hariue;its lower eel-4e curled inwardly to l'orin an internal thing U closetencircling the. hotly t tho post. M: the upper ends the sit-Pres arethreaded and received in rorrespontllug hides llitlod and tapped in thelower plate 1) of the tophar. The upper plate I) is of sheet metalrolled in channel form and is held to the lower plate by stud-rivets l).thus ru-ovhh ing a space in which is located a lu king slide 1*) movedlongitudinally h a screw ti having a squared end E tor the reception ofa corresponding key. not shown. hr which the screw is turned in its am)not I)".

On the upper end of ea h post ll is a flared head It of a diameter atthe top to match the interior of the sleeve t to permit the post to movetelescopically therein while prevented from complete withdrawal lvv theengagement of the head with the llanee U. and the flat upper face ot'thehead is drilled axially as at b to receive a spur h riveted to theinterior of the upper plate l of the top-bar.

\Vhen the top and bottom-bars are forced toward each other to the limitpermitted hy the. posts B the latter are anchored to the upper plate bythe engagement of the. spurs F with the recesses 71 and the lateralstrains due to the thrust of the slotted locking-slide R against. theheads are thus strongly resisted.

By reason of the flared or coniealtorm of the heads the posts areetlectually held against withdrawal when engaged by the lOPlUn J-Slttltand accidental release is thus prevented while the reinforcementafforded by the spurs permits the locking-slide to he very iirmly thrustagainst the heads without danger of distortion or other injury.

G is acompressonbar through which the posts extend. composed of twoplates or sections separated by studrivets G and containing alocking-plate H operated by a screw G in a fixed nnt- Gfl'similar to thelocking-slide E above described. The function of the compressorbar is tohold the leaves beneath it in close contact with the bottom-bar and eachother when the number is less than sufiicient to fill the space betweenthetop and bottom-bars. The comother forms of locking devices scopicallyin said sleeve,

pressor-bar is notched on one edge, as at g, to permit its applicationto and removal from the osts, and the locking-plate is similarly noteed, as at h, for the same purpose.

The notches g are preferably inclined or angular the better to resistdirect strains and the notches h are each similarly inclined and formedwith an offset partially encircling the post when adjacent thereto, thuspermitting the compressor-bar to be raised or lowered on the posts byslackening the grip of the locking-plate H thereon while stillmaininsure against complete removal; the com pressor-bar may hefreed forsuch removal when desired by turning back the screw Gr far enough toallow thestraight sides of the notches It to coincide with those of thenotches g, thus affording sufficient space for the assage of the postsas the compressorbar 18 drawn'away in an angular direction.

Modificationsina be' made in the forms i and proportions without dodarting fromthe invention, and parts may e used without the whole. Otherforms of compressor-bars may be substituted for the bar shown, and maybe used in place of the locking-slide and lockingplate illustrated anddescribed.

I claim 1. In a loose-leaf binder, a bottom bar, a top bar, postssecured to said bottombar and movable with relationto the top bar,conical heads on said posts and locking means carried by said top barand constructed to engage the conical portions of said heads.

2. In a loose-leaf binder, a top bar, a bottom-bar, posts securedthereto, a'sleeve inclosing .the upper portion of each of said postsandsecured to said top-bar, a head on each of said posts arranged tomove teleand locking means carried by said top-bar-and constructed toengage said heads.
